摘要：Amorphous Co-Zn alloy nanowire arrays with diameter of about 40 nm were fabricated in anodic aluminium oxide films by the electrodeposition method Transmission electron microscope result shows that the nanowires are regular and uniform Selected area electron diffraction and X-ray diffraction results indicate that the structure of nanowires is amorphous. Vibrating sample magnetometer is employed to study the magnetic properties of nanowire arrays at room temperature. The results show that the arrays of nanowires exhibit uniaxial magnetic anisotropy with the easy magnetization direction along the nanowire axes owing to the large shape anisotropy. When the applied magnetic field is parallel to the wire axis, the coercivity and squareness of the nanowire arrays decrease with increasing Zn concentration. (C) 2009 Elsevier By. All rights reserved
